Patent GB-394359-A (GB)
Title: Manufacture of partially acetylated cellulose
IPC: C08B3/06
Filed: 1931-12-23
Abstract: Natural cellulose in the form of fibres, threads, fabric, paper, or the like is partially acetylated in a bath comprising an acetylating agent and a non-solvent for cellulose triacetate.  In order to obtain partial acetylation, the amount of acetylating agent used may be insufficient, or a normal amount of acetylating agent may be present such as is used in the production of the triacetates, in which case the time, temperature, and/or strength of solution are insufficient to acetylate fully the cellulosic material.  For example, when working according to the first method, the acetic anhydride may be present up to nearly twice the weight of the cellulose, and the reaction allowed to proceed as far as it will within a reasonable time.  As non-solvents, carbon tetrachloride, benzene, and toluene are mentioned.  In an example, cotton, cotton thread, cloth, or paper is pretreated with glacial acetic acid and a catalyst comprising a mixture of sulphonic acid and phosphoric acid, pressed off, and acetylated by means of acetic anhydride (130 per cent of the weight of the cellulose) in the presence of carbon tetrachloride.  The acetyl value of the product is 24-25 per cent.  Threads are preferably treated in hank form, and fabrics in the form of a bolt where the weave is not too close.  A preferred form for acetylating thread, fabric, or paper is by the continuous method wherein the thread, fabric, or paper is fed through the acetylation and washing baths, and the drying apparatus.  The treating baths may flow counter-current to the cellulosic materials.  The products have a high electrical resistance and may be used in the production of insulated wires, or as dielectrics in condensers and transformers.

Title: Improvements in liquid meters
IPC: G01F3/18
Filed: 1938-12-06
Abstract: 520,919. Liquid meters. BLUM, H. L. Dec. 6, 1938, No. 35601. Convention date, Dec. 6, 1937. [Class 69 (ii)] A reciprocating type. liquid meter of the kind in which a valve gear is moved suddenly at the end of the stroke, is provided with a valve actuated means operating in parallel and spaced relationship with the valve seat and with a certain freedom relative thereto The meter is constituted by a central block 11 carrying cylinder blocks 19 in which the reciprocating pistons 131 are connected by a rod 125 which has flanged members 130. Contacting with the flanges is a roller 121 on the end of an arm 119 secured tc a spindle 89. The spindle is continued in one direction to operate a recording mechanism 101 and in the other direction to carry a lever 157 which is adapted to operate the valve gear. In a modified form the lever 157 is replaced by lever 227. As the piston moves to the right, the shaft 89 is given a counter clockwise movement which is transmitted to the lever 227. The notch 245 in the valve actuator plate is engaged by the righthand pawl 209 so that the valve recess links up the port 63 and the right-hand port 45 to permit the right-hand cylinder to discharge and the left-hand one to fill. The counter clockwise movement of the lever 227 is transmitted to the lever 235 by a pin-and-slot connection 229, 243, and as the roller 241 passes the centre line between the pin 217 on the actuator plate and the pivot 240 of the lever 239, the spring 253 is stressed and the actuator plate is moved over. Temporarily, this movement is prevented by the engagement of the pawl and notch, but eventually lever 227 contacts with the left-hand pin 252 and when the stop face on the piston contacts with the cylinder abutment then the pawl 209 is withdrawn and the valve actuator plate will rotate until it is locked by the left-hand pawl 209 engaging the corresponding notch 245. This results in the valve 205 being shifted so as to couple the port 63 with the left-hand port 45 whereby the left cylinder is discharged. The discharge is effected through port 65 whilst the inlet to the meter is through a. passage 67. In a modification, the piston members are mounted on the rod 125 so as to be adjustable axially whereby the stroke between the flanges 130 is also adjustable.

[Class 108 (iii)] [See also Groups VIII and II] A resilient mounting for the work-support of a laundry press or for the basket of a hydroextractor comprises a supporting member mounted in a housing with an intermediate layer of resilient material and provided with means which, while permitting rocking of the supporting member within the housing, prevent relative rotation thereof. In the form shown in Fig. 1 applied to a laundry press, a stem b is formed on the underside of the work-support a and terminates in an inverted truncated conical portion which is received in a correspondingly shaped socket d with a rubber sleeve c interposed between the stem and socket. Splines are formed on the inner and outer surfaces of the sleeve to engage corresponding grooves in the stem and socket to prevent relative rotation between these members. In the form shown in Fig. 3 a hollow stem f is provided with a flange h and splined rubber buffers i are confined between the stem and socket and are splined thereto. In Fig. 4 relative rotation between the stem and socket is prevented by an annular member m pivoted at two diametrically opposite points to brackets n secured to the socket and at two other opposite points to pins o secured to the stem. To permit relative vertical movement the ring m is slotted at the parts p about the pins o. Spring padding may be substituted for the rubber member. Any of these resilient supports may be used for supporting the basket of a hydro-extractor. In Fig. 9, for example, a hollow member 19, in which the bearings 20, 21 of the basket shaft are secured, is supported in a boss 15 secured to a bed plate 13 with a resilient collar 17 interposed between the members 15 and 19 and splined thereto to prevent relative rotation between these members.

Abstract: 1525604 Supervising interstation signalling SIEMENS AG 4 Sept 1975 [11 Sept 1974] 36380/75 Addition to 1398961 Heading H4L A data transmission system having a monitoring signal of at least one bit interposed at regular intervals into the data, comprises a plurality of sections connected by intermediate stations, wherein if the monitoring signal is incorrect when received the station transmits at least one bit in inverted form back to the preceding station. The inverted bit may effect automatic switch-over to another channel. The receiving and transmitting sections of an intermediate station in a 30 channel PCM system are shown in Figs. 1 and 2 respectively. A first shift register SRI receives data from input PE and link timing pulses from input TE. Read-outs RKL, MWL extract respectively the frame synchronizing word and the message word, timing pulses for RKL, MWL being provided by a first pulse generator TZ1. Bits, 5, 6 and 7 of the message word are supplied to an acknowledge and address analyser RAW. A first timing pulse monitoring unit TU1 produces a high level at ouput A2 in the event of a timing fault. A synchronization monitoring unit SYNC receives bits 2, 3, 4, 6, 7 and 8 of the frame synchronizing word, and bit 2 of the message word, the outputs A1, B1 being high in the event of a fault, e.g. if the frame synchronizing word is incorrect several times consecutively. A gate NOR1 having inputs A1, A2 produces an alarm criterion A which is low for a fault. A second shift register SR2, Fig. 2, receives a frame synchronizing word and a message word from transmitting logic units RKS and MWS respectively, bit 5 of the frame synchronizing word being inverted in the event of a fault by a direct input from A. Inputs from A also control the transmission of frame timing pulses from TZ1 to TZ2 via gate AND1, and the transmission of link timing pulses from TE to TZ2 via gates NAND1 and AND2, the pulses from TE being replaced by pulses from a generator TG if the A input applied to gate OR1 is low. A scrambler SC has its output connected to a gate NOR2 which also receives an A input via a switch U. Scrambler SC produces a high level output while the frame synchronizing and message words are being passed from SR2 to signal output PO, so that these words are not scrambled irrespective of the level at input 1 of NOR2. If the A signal to input 1 of NOR2 is low, or if input 1 of NOR2 is earthed manually by switch U, the output of SC is fed in inverted form to gate EXOR1, so that a scrambled signal is produced at output PO.
